THREE-BARRELED GUN.

BPECIFICATION forming part of Letters 2a.tent No. 278,688, dated June 5, 1883.

Application filed April 26, 1882.

To all whom it may concern:

as will enable others skilledin the art to which,

it pertains to make and use the sameJ" -My invention 1 relates to an improvement in firearms, and more particularly to thatzclass thereof designed for sporting purposes, the object of the invention being to attach arifiebarrel to he top and between. the barrels of a double-barreled breech-loading shotgun, and

to provide lock mechanism forfiring the rifleba1'rel,whiclr;s'11all be arranged tobecperated by the firing mechanism of either of'th'e sh'ot barrels, and yet to be so far independent of such "mechanisms that they willnot be dis,

turbed in the performance of. their ipeculiai functions.

'XVith these ends in view my invention consists in certain details of construction and combinations of parts, as will be fliereinafter dea View in side elevation of a combined shotgun and rifle constructed in accordance with my invention. Fig. 2 is avertical longitudinal sec; tion, showing thelock mechanismof the rifle--.

barrel audits connectionwith the firing mech anism of one of the shot-barrels, and Eig'jfi is a view in transverse section of the shot and rifle barrels.

I The rifle'A attacnedito'tlre top of and-between the two shot-barrels B inf any desired manner, the said barrels beinglsecured to the" breech-block C by any approved means. The lock-frame D, inclosing the devices for firing the vrifie bari el, is secured to the rearwardly extending arm E of the breech'block by a screw, F, and by a lug, G, made integral with or at: sached t0 the lower face of the outer end of the lock-frame, and adapted to be received within a recess,H, formed in the breech-block, the particular function of the said lug being to enable the lock-fram'eto withstand the re coil resulting from the discharge of a cartridge in the rifle-barrel.

A firing-pin, I, adjusted to have longitudinal reciprocation inthe forward end of the lock- (No modem frame, is actuated by the plunger J, which encircled byihe spiral spring K. The upper facepf the s'aid firing-pin is cut, away, to receive thecnd of a screw, L, which limits the -ecilirohtOrymovement ofthe pin and preveutsitfrom being displaced. .If desired, how ever-{the firing-pin may be attached directly to the outer end of the plunger, although the constructi onshown isv preferred. The rear end of the plunger is journaled in a ring-shaped bearing, M, which is transversely slotted and held in positionby a pin, N, the lower end of the said-bearingbeing cut away, to permit the dog F to engage with the notch 0, formed in th'elow'er side of the plunger, when the same is retr'actedyas ihown in the drawings, bythe (BOCKliigfilII-I-P, the'lower' end of whichis pivoted to the extreme rear end of the lock-frame D. The nearend of the plunger, as wellns the lug Q, formed on the innerface ofthe cockingarm, is vertically slotted to receive the conne'cting-link RL- A spring,- S, arranged to impinge against the dog, is designed tomaint-ain it in a normal condition of readiness to engage with the slot O,'-fornied in theplunger, as described.

In-firing-the rifle barre'lthe engagement between the plunger and dog is broken by the pin- T, which reciprocates in a vertical hole formed in the gun-stock, the upper end of the said pin being arranged to impinge against the lower face of the deg F, while itslower end is supportedupon the edge of one of the plates U, formed integral with'or attachedto the trigge'rs V. When the plate upon which the pin rests is moved by retracting the trigger, the pinwill be elevatedi'and impart its motion to the dog, which will be rocked on its pivot and released from-its' engagement with the plunger,

which will at once be proj ected against the fir ing-pin by the force of thespring K, and the firing-pin will be suddenly projected against the cartridge in the rifle-barrel, the cohcussion resulting in the discharge thereof. It will, however, be perceived that if the plunger is not retracted and engaged with the dog F pre vious to retr'acting the trigger the only result tl1crc0f,-'so far as the firing mechanism is concerued, will be to rock the dog IE", and therefore, although by engaging the dog with the ,plunger the rifle-barrel may be fired by the firing mechanismof one of the shot-barrels, that such mechanism is in no wise embarrassed by the auxiliary function which it is made to perform. If desired, however, a third and independent trigger may be provided to actuate the firing mechanism of the rifle-barrel. -As now constructed the plunger is retracted by the cocking-arm; but other means may be employedto effect the same result.

As the rifle-barrel and its firingmechanism IO 7 are virtually independent of the shotgun barrcls and their firing mechanisms, any doublebarreled shotgun may be provided with a riflebarrel and appropriate lock mechanism, after its completion, at a comparatively light ex- I 5 pcnse.

I would have :it" understood that I do not limit myself to the exact construction and combinations of parts herein shown and described, but that I holdmyself at liberty to makesuch 2o slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

2 5 1. The combination, with a doublebarreled breech-loading shotgun having a rifle-barrel attached to the top of andfbetween the shotbarrels, of independent mechanism for firing the rifle-barrel, and devices substantially as described, connecting said firing mechanism with both of the triggers of the shot-barrels, whereby the retraction of the firing-p1unger of the rifle-barreIwilI enable said plunger to be released by'either oncof said triggersinr firing the rifle.

2. The combination, with a double-barreled breech-loading shotgun having 'a rifle-barrel attached to the top and between the shot-barrels, of a breech-block having a recess in its upper face, and a lock-frame to inclose the fir- 4o ing mechanism of the, rifle-barrel, said frame being provided on its under face with a lug breech-loading shotgun having a rifle-barrel attached to the top of and between the shot-' barrels, of independent mechanism for firing the rifle-barrel, said mechanism being mounted in a frame removably secured to the top of the breech-block, and devices, substantially as (10- scribed, connecting said rifle-firing mechanism with both of the triggers of the shot-barrels, whereby the retraction of the rifle-firing plunger will enable it to be released by either one 5 5 of the triggers, substantially as set forth.

4. The combination, with a double-barrelcu breech-loading shotgun having a rifle-barrel attached to'thc top and between'the shot-bar- I rels, of independent rifle firing mechanism '60 mountedon the top of the breech-block, rod '1, and the triggers V of the-shotgun, substantially as set forth. g p

In testimony whereof I have signed thisspecification in' the presence 'of two subscribing witnesses. i
